Key Features & Benefits at a Glance
- Superior holding power from alloy steel construction and Rockwell C45 hardness prevents loosening under high vibration and load.
- Maximum torque transmission via the 4 mm hex drive and headless design, allowing for flush installation in tight spaces.
- Reliable coarse threading (M8 x 1.25mm) ensures faster installation and robust grip in a wide range of materials.
- Precision Class 5g6g thread fit guarantees consistent engagement and reduces the risk of cross-threading during assembly.
- Durable flat tip provides a secure, non-marring contact point for precise component positioning.
- Full compliance with DIN 913 and ISO 4026 standards ensures dimensional accuracy and interchangeability in global applications.
- Environmentally responsible manufacturing with RoHS 3 and REACH compliance meets stringent international regulatory requirements.
Professional Applications & Engineering Value
This M8 set screw is engineered for demanding industrial applications where vibration resistance and precise alignment are critical. The high-strength alloy steel and Rockwell C45 hardness provide exceptional shear and tensile strength, solving common failure points in machinery, automotive assemblies, and precision tooling. The headless design with a hex drive allows for a completely flush finish, making it ideal for securing collars, gears, and pulleys on shafts without protruding hardware. Its coarse metric thread (1.25mm pitch) and Class 5g6g thread fit ensure quick, reliable installation and long-term holding power, reducing maintenance downtime and improving operational safety in right-hand thread configurations.
Specification Summary & Compliance
This metric set screw features an M8 x 1.25mm coarse thread with a Class 5g6g thread fit for precise dimensional tolerances. It is manufactured in accordance with DIN 913 and ISO 4026 specifications, ensuring consistent quality and performance. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for use in regulated industries and environmentally conscious supply chains.
